Beryl-spangled Tanager

Beryl-spangled Tanager (Tangara nigroviridis)

The Beryl-spangled Tanager, Tangara nigroviridis, is a brightly colored tanager that can be found in the Andean cloud forests.

The Andean subtropical region from Venezuela to Bolivia is home to this small tanager. Unmistakable – entire body is boldly spotted in bright blue-green. This contrasts sharply with the black mask and back. No other tanager is as spangled. Both sexes. Mixed flocks are common between 1,500 and 2,500 meters, in forest as well as at the edges or second growth.

Beryl-spangled Tanagers are found along the eastern slopes the Andes, from Colombia to Bolivia. It is found in Ecuador at an elevation of 700-2,500m (2,300-8200ft), and slightly higher in Peru – 1,500-2900m (4900-9500ft). It is found in second growth and humid montane forests.

The Beautiful Beryl-spangled Tanager

Tanagers are a family of birds that includes the Beryl-spangled Tanager. Around 240 species, mostly brightly-colored fruit-eating bird species, are found in the region.

Tanagers can be small or medium-sized. The white-eared conbill is the smallest species. It measures 4 inches and weighs only 0.2 oz. This makes it smaller than the short-billed Honeycreeper.

The magpie tanager measures 11 inches long and weighs about 2.7 oz. The white-capped Tanager is the heaviest, weighing 4.02 oz. and measuring about 9.4 in.

The size and weight of both sexes is usually similar. Tanagers can be brightly colored or black and white.

Males tend to be more colorful than females or juveniles. The wings of most tanagers are rounded and short.

The bill shape seems to be related to the species foraging habits.
